Moisture Processing Unit FMP-2
Figure 1: Moisture Processing Unit FMP-2 (two channel version)
Brief summary:
The FMP-2 is a processing and displaying unit, which, in combination with well proven ARNOLD
moisture sensors, processes the moisture and temperature of a material, displays the both
quantities and and passes them to the process control.
The FMP-2 is not only processing the sensor signals, but also providing all needed supply
voltages, so no additional supply unit is needed.
Up to two independend moisture sensors can be connected to the two channel version of
FMP-2.

The operation of FMP-2 is intuitive and simple and is supported by a big touch screen and highresolution graphic display (LCD). Thanks to the use of modern SMD-technology the device is
very compact.
Fife different calibration curves per channel with up to 40 calibration points each can be
programmed by the help of an intuitive teach-in procedure. A linear interpolation is used
between the calibration points.
All calibration points are comfortably stored and edited, either by entering the data by teach in of
the calibration points, by calibration table or by directly moving the points in the displayed
calibration curve on screen.
The moisture signal can also be displayed in the “Show Measure Curve“ mode, like with the well
known transient recorder, which can be very helpful during the first steps, when the FMP-2 is
put into operation and during the calibration procedure.
Additionally, in „manual setting“ mode an control signal can be set and emitted by the output of
FMP-2, to simulate certain moisture signals.
The FMP-2 is standardly emitting 0-10V, optionally 0-20mA or 4-20mA. The FMP-2 can
communicate with the following process control also via the built-in USB- and RS485-interfaces.

1.
General points:
The second generation of ARNOLD‘s Moisture Processing Unit „FMP“ is now available in a two
channel version. Up to two independent moisture sensors can be connected to the FMP-2.
More, up to two independent PT100-temperature sensors can be connected, mounted in the
moisture sensors or external.
All cables are connected to the back plane of FMP-2 by the help of pluggable clamping bars.
Standardly, the FMP-2 provides an USB-interface and a galvanically isolated RS485-interface,
which allows the control of the FMP-2 and transmission of signals over very long distances
(RS485).
2.
Safety hints!
The FMP-2 is designed to be installed in a control console. So, the device doesn’t contain a
mains switch. The On-Off-switching must be provided by an external mains switch at the control
console.
The device is only allowed to be opened by qualified personal! And only with unplugged mains
cable, of course!
The device must be connected to mains by using a three wire cable, which includes the
protective earth wire (PE)!
The FMP-2 is designed to be mounted into a switch panel. A rubber gasket supplied with FMP-2
seals the device at the switch panel. The back of enclosure contains vent openings and isn’t
waterproof!
The back of enclosure must be aerated to remove the internally dissipated heat. Because of
this, other devices on the switch panel should not be mounted too close to the FMP-2.
The FMP-2 is protected against overload by self-resetting fuses (polyfuse).

Different measuring modes of FMP-2:
The FMP-2 is available as one channel version (monodevice) or as two channel version
(duodevice). The operation of both devices is identical.
The desired “Measure Mode” is chosen in the „Settings“ menu:
4.1 Measuring mode „measure“:
In this fatory presetting mode the moisture is continuously measured and displayed in realtime. If the display reading appears unstable a signal filtering (moving average time) can
be added.
4.2 Measure-mode „start/stop“:
The FMP-2 provides independend and galvanical isolated start/stop switch inputs for each
channel. The measurement is controlled by this input: 0V = stop and +24V = start.
The status of the according switch input is displayed in the status line of „main menu“.
This useful feature allows to measure the moisture during a certain period of time, for
instance for the duration of dosage.
Immediately after the start signal has become active (+24V = start) the measurement of
moisture begins. For the whole duration of dosage the FMP-2 continuously calculates the
current average value of moisture and displays it.
Immediately after the switch input has become inactive again (0V = stop), the
measurement stops and the last calculated average value is permanently displayed, until a
new start signal arrives. Also, at the signal output of the FMP-2 the last calculated average
value is permanently emitted.
By other words, the start-stop-feature allows to measure the averaged moisture during a
certain period of time. Afterwards the calculated average value can be taken over by the
process control.
As long as the last average value is captured, the status line on screen displays „stop +
hold“.

100485.doc
4.3
Measuring mode „automatic start/stop“:
In this measuring mode the FMP-2 also continuously calculates the current average value
of moisture for the whole duration of dosage, but here the measurement is not controlled
by the switch input but by the moisture signal itself. When there’s no material at the sensor
before and after the period of dosage, but only during the dosage, then the begin and end
of material flow can easily be detected from the height of moisture signal: When there’s no
material at the sensor, then the moisture signal is nearly 0%, of course. So, everything to
do is to choose a suited threshold, so that the measurement is started, whenever the
moisture signal is higher than the threshold and is stopped, whenever the signal is smaller
than the threshold.
This measuring mode is highly useful, when the sensor is mounted below the dosage
outlet of a silo, for instance.
A suited threshold for this automatic start/stop, called „lower signal limit“, can be set in the
„stettings“ menu.
During the measurement the message „auto start“ is displayed in the status line of the
„main menu“. At the end of the measurement the last calculated average value is
permanently displayed, until a new start signal arrives. Also, at the signal output of the
FMP-2 the last calculated average value is permanently emitted. As long as the last
average value is captured, the status line on screen displays „stop + hold“.
4.4 Start delay with the measuring modes „start/stop“ and „automatic start/stop“:
In the „Settings“ menu you can additionally set a start delay time, which causes, that the
measurement does not begin immediately after activation of start signal, but only after the
end of this start delay time.
The start delay helps to eliminate irregularities of material flow immediately after the start,
for instance.
Or you can suppress a certain „dead time“, means the period of time the material
eventually needs to flow to the sensor.

General notes on operation:
5.1 Distinguishing between the channels:
In each display window there is on top of the screens a small symbol (number „1“ or „2“, in a
small square), which informs about being in a menu of channel 1 or channel 2. Here is an
example: You see the „main menu“ of two channel version of FMP-2:
Left side is for channel 1 and right side is for channel 2.

5.2 Unlocking of protected menus:
To protect important settings of FMP-2 against unintentional misadjustament, most of the
settings are locked. To change a certain setting you must first unlock the menu by a certain
sequence of keystrokes:
1.) Unlocking in the „EDIT“ menu:
2.) Unlocking in the „Settings“ menu:

5.3 Verification of successful unlocking:
In the „Settings“menu:
The first setting in this menu becomes highlighted. Press the cursor buttons to choose the
settings you want to change.
In the „EDIT“menu:
New push buttons appear in the „EDIT“ menu.
Without unlocking the calibration curves can only be displayed, but not changed. You need to
unlock the menu to be able to make changes of calibration.
5.4 Storing the changes of settings:
You must always press „ENTER“ to store the change of each setting.
5.5
Some notes on „Range“:
When setting up a new calibration curve in the „Curve initialisation” menu you must always set
the according „Range“. The „Range“ defines the maximum range of moisture of this calibration
curve. The „Range“ also defines the moisture at maximum output signal of FMP-2. Example:
A Range of 20% in combination with a signal output of 0-10V gives 0V at a moisture of 0% and
10V at a moisture of 20%. Between these limits the signal linearily increases by 0.5V every 1%
increase of moisture.
The same when the output emits a current of 0-20mA.
When emitting a current of 4-20mA, then 0% corresponds to 4 mA und 20% to 20 mA, linearily
increasing.
Finally, the „scale“ also determines the available range for the signal limits and alarm thresholds
in the „Settings“ menu:

At the top of display window the name of selected curve, means the product is displayed. The
editing of curve name, means product, is done in the „calibration“ menu.
When there are still no calibration curves available, means after the first power-on of FMP-2,
then the voltage (or current) measurement of sensor signal is automatically selected (default).
Because there is no calibration curve available then, no moisture can be displayed at this
moment, of course. In this case the sensor signal is displayed in V (or mA). (See also „12.
Product menu“)
If there’s no temperature sensor connected to the FMP-2 (or no temperature option is
available), no temperature is displayed.
Below the measured values the measuring mode and the signal average time is displayed for
each channel.
Below of that you will find the status lines. Here status and error messages (alarms) are
displayed, again independently for each channel.
Right at the bottom you will find the four buttons „menu 1“, „product channel 1“, „menu 2“ and
product channel 2“.
By pressing the „menu“ buttons you can reach a submenu, from where you can go into three
further submenus: „Show Measure Curve“, „Manual Settings“ and „Settings“.
By pressing the „Product“ buttons you will enter the „Product“ menu, where you can select one
of five calibration curves per channel and where you can select the help function „voltage
measurement“ (current measurement). From here you can reach the „calibration“ menu, by
pressing the „EDIT“ button.
8.
Channels average measurement:
If both moisture sensors are mounted at the same silo, for instance, and you are interested in
the average moisture signal from both moisture sensors, then you can activate the displaying of
average value from both channels in the „main menu“. At the same time also the average
temperature signal from both temperature sensors is displayed.
To activate the displaying of average value from both channels, set „channels average
measurement = ON“, in the „Settings“ menu.

For the selected channel the moisture signal can be displayed in a similar way as a transient
recorder does. Here, the signal „runs“ from the left side to right side on screen. Having reached
the right side, the signal starts again at the left side. The time period needed to run from the left
to the right side can be set by the two arrow buttons for 5, 25, 50 and 100 seconds.
This option allows to display the moisture signal in an easy way during the whole dosage period
and helps to analyze the dosage process.
You can stop the measurement at any time by pressing the „RUN / Hold“ button. At this
moment the symbol „hold“ begins to blink and the last reading remains „frozen“. Press again the
„Run / Hold“ button and the measurement continues.
This displaying option, by the way, helps to find an optimum averaging time constant, if any
needed.

This option allows to set a moisture signal by hand and emit it at the output of FMP-2 (0-10V or
0/4-20mA, whatever is available).
Standardly the output emits the measured moisture signal. But when the „Manual setting“ is
activated, the output emits the value set by hand.
In this case the moisture sensor signal is only displayed in the „main menu“.
The hand setting option allows to simulate certain measuring situations and helps to analyze
and optimize the process control.
This option also allows to send a signal to the process control, if the sensor is disconnected for
inspection purpose, or similar. Or you can calibrate the input of an A/D-converter of process
control, for instance.
To remember the operator that the signal is set by hand, in the „main menu“ in the status line
the warning „hand setting = X%“ is displayed.
When a sensor is connected to the FMP-2, in the „main menu“ the sensor signal is displayed,
but the output will emit the value set by hand.
In the „hand setting“ menu there are four buttons: Two buttons to set the hand value, the button
to activate and deactivate the hand setting and the „ESCAPE“ button.

called „not-occupied“. To each product there is the range displayed at the right side. „Range“
means here the maximum range of moisture.
There is also the button „Voltage measurement“ („Current measurement“). When pressing this
button, the sensor signal is directly displayed in „V“ or „mA“. This status is also displayed in the
„main menu“. This feature is very interesting for preadjustment of the sensor signal range.
Press the „ESCAPE“ button to go back to the „main menu“.
Press the „EDIT“ button to go to the „calibration“ menu (to the curve you have selected by the

13.1 Unlocking the „calibration“ menu:
When pressing the „EDIT“ button you will enter the locked „calibration“ menu (see figure 11).
„Locked“ means, that the curve list, the selected calibration curve and the curve table is visible,
but that you cannot change any calibration data.
In the locked „calibration“ menu some buttons are missing, which become visible in the
unlocked „calibration“ menu (see figure 12)
To unlock the „calibration“ menu a certain sequence of keystrokes is needed, as already
mentioned above:
First, press the left arrow button (-), then the right arrow button (+), again the left arrow
button (-) and again the right arrow button (+).
Afterwards the unlocked „calibration“ menu appears, according to figure 12.
The unlock feature shall prevent important settings from being changed by non authorized
persons.
Leaving the „calibration“ menu will automatically activate the lock again.
13.2 Curve initialisation:
Before entering calibration points you must first configure a new curve by pressing the
„Curve initialisation“ button in the unlocked „calibration“ menu.
„Curve initialisation“ means to enter a curve name (e.g. sand 0-4mm) and to enter the prevered
range of moisture (e.g. 20%).
Calibration curves are configured in the „calibration“ menu and can also be edited and displayed
here. Optionally, calibration curves can also be entered and edited by the help of calibration
table.
Each calibration curve can contain up to 40 different calibration points. Between the points a
piece wise linearization is provided, means neighboured points are connected by a straight line
(see figure 14).
In the „calibration“ menu the calibration curve is preselected, which was formerly selected in the
„product“ menu. But it is also possible to select another curve in the menu “Curve initialisation”.

Figure 13: „Curve initialisation“ menu
You can do two things in this menu:
1. You can enter the curve name and range, means you can initialise a new curve.
2. You can delete complete curves.
Move the cursor by the help of right/left buttons.
To enter the curve name press the „ABC“ button. To enter the range press the „123“ button.
This buton is displayed if the cursor is in the field “Range”. After entering of each data press the
„ENTER“ button. Then, back in the „Curve initialisation“ menu, press again the „ENTER“ button.
Now you can enter the calibration points. A courve needs at least two calibration points.
14.2 Deleting a curve:
You can delete a curve in the „Curve initialisation“ menu. Take care, deleting a curve
eliminates all data of this curve, means the curve is entirely deleted!

Now press the „DEL“ button. You can undo the deletion by the help of „UNDO“ button!
Attention: You must press the „UNDO“ button immediately after the „DEL“ button to undo
the deletion.
14.3 Entering the calibration points:
Attention:
Before entering the calibration points the moisture sensor itself must be
precalibrated, so that the signal range is within 0-10V (0/4-20mA) for the
desired scale.
14.4 Hints on calibration:
First, a static calibration of FMP-2 by the help of prepared buckets containing material of
well known moisture has to be carried out. This „static“ calibration curve can be optimized
by a „dynamic“ calibration later, when the sensor is mounted in its final application and
further calibration points are added.
The graph of calibration curve can help to find optimum calibration points: A proper
calibration curve isn’t angular but smooth!
14.5
Three ways to enter the calibration points:
In the „calibration“ menu there are the following three ways:
14.5.1
Calibration by the help of „silo“ button („dynamic“ calibration):
By the help of „silo“ button (left of „0/3“ button in figure 12) an averaged calibration point
can be gained, which is taken during the dosage process. For this, press the „silo“ button
as long as the dosage process lasts. But start the pressing only when the material has
begun to flow evenly and stop the pressing before the dosage process ends. By this, a
representative measurement during the whole dosage process is guaranteed.

The calibration by the help of „silo“ button provides very reliable calibration points.
While the „silo“ button is pressed, at the left side of screen the averaged value is
displayed. When the button is released, the final average value is displayed in big letters.
At the same time at the right side of screen the „ Calibration reference “ is displayed.
Enter the reference moisture (calibration point) by the help of arrow buttons and press
the „ENT“ button to store the data. The calibration point can be changed later, by
changing the entries of according calibration table.
14.5.2 Calibration by the help of „0/3“ button („static“ calibration):
By the help of „0/3“ button (see figure 12) you can generate a calibration point by taking
the average of up to three measuements in a row. This option is very useful, if the
moisture measurement of a certain material is difficult, means if it depends on how you
prepare the sample (surface) or how you press the sensor onto the sample. So, when
you have the samples in buckets you should use the this calibration mode.
If the average shall be taken from only one or two measurements, press the „ENT“ button
to leave the taking of samples. Afterwards, at the right side of screen the „Calibration
reference“ is displayed. Enter the reference moisture (calibration point) by the help of
arrow buttons and press the „ENT“ button to store the data. The calibration point can be
changed later, by changing the entries of according calibration table.
14.5.3 Entering a curve by the help of calibration table:
Press the „Calibration table“ button to enter the „calibration table“ menu.
You can enter, change and edit all the table data by the arrow buttons. Each change of
data must be stored by pressing the „ENTER“ button.
After pressing the „ENTER“ button the data of table is automatically arranged according
to size.

Attention: Like the „calibration“ menu this menu is locked, to prevent important settings from
being changed unintentionally. To change the settings, the menu must first be unlocked by a
certain sequence of keystrokes:
First, press the left arrow button (-), then the right arrow button (+), again the left arrow
button (-) and again the right arrow button (+).
By the help of arrow buttons you can select and edit the settings. To store the changes please
press the „ENTER“ button.
15.2 Setting options in the „Settings“ menu:
Software version:
The software can be updated in the future by the help of an internal
connector.
Language:
You can select the following menu languages: German, english,
french and spanish. Other languages possible.
Averaging time:
Settable from 0 to 100 seconds. The averaging time plays only a role
with the continuous measuring. With the start/stop and automatic
start/stop measuring modes the average is taken over the whole
dosage period , of course.
Measure-mode:
Three measuring modes are available:
Measure (continuous measurement)
Start / stop (activation via external switch input: start = +24V, stop =
0V)
Automatic Start / Stop (Activation when reaching a certain
threshold).
Start delay:
Only available with the measuring modes „start / stop“ and
„automatic start / stop“. The start of measurment is delayed by the
start delay time.

Possible settings: 0.1...0.9...1...100 seconds.
The start delay helps to eliminate irregularities of material flow
immediately after the start, for instance. Or you can suppress an
eventual „dead time“, means the period of time the material needs to
reach the sensor.
Channels averaging:
On / Off. Only available with the two channel verson.
When being activated the moisture and temperature measurement is
the average from both channels.
Signal limits:
By the help of signal limits you can limit the displayed and emitted value of moisture
measurement.
Assume the range was set to 20%, then the range of moisture measurement is 0-20%. By the
help of signal limits you can now furtherly limit the displayed and emitted value of moisture
measurement: If you set the lower signal limit to 3%, for instance, then a sensor signal in the
range of 0...3% will result in a reading of 3%.
The same with the upper signal limit: If you set the upper signal limit to 16%, for instance, then a
sensor signal in the range of 16...20% will result in a reading of 16%.
By other words, the signal limits allow to limit the signal emitted at the output of FMP-2 and to
limit the displayed value of moisture measurement.
For each curve a lower and an upper signal limit can be set.
Alarm limits:
By the help of alarm limits you can set certain thresholds, which activate individual alarms when
being exceeded. These alarms are not only displayed in the status line of „main menu“, but can
also activate the alarm relays.
For each curve a lower and an upper alarm limit can be set.
Assigning of alarm relays:
The FMP-2 contains two independent alarm relays. Both relays can be assigned to both
channels and to all alarms.

A second order curve is calculated from the table data and is added to the measured moisture.
To activate the temperature compensation, set „Temperature compensation to “On“.
Because the temperature effect on moisture measurement is rather little, there’s only one
temperature compensation table available for all the products (calibration curves). The
temperature compensation can be turned-on or –off.

The FMP-2 is designed to be installed into a control panel. It has to be protected against
humidity and dirt. A rubber gasket supplied with FMP-2 seals the device at the control panel.
The ambient temperature must be within the limits. Also, the device must be aerated to allow
the remove of internally dissipated heat.
Due to the design the FMP-2 needs an external mains switch.

Quickstart: Setting up a curve:
In the following we want to carry out a „static“ calibration on channel 1. Then, at the end of this
chapter, we will briefly discuss the „dynamic“ calibration. (Please have a look at the „summary of
menus“ on page 11, to find the various submenus.)
Precalibrating the moisture sensor:
Before the moisture sensor can be used for measuring of moisture and feeding the FMP-2 with
its signal, it must be precalibrated, to guarantee, that the sensor signal is 0V at minimum
moisture and 10V at maximum moisture. If the moisture sensor isn’t precalibrated by the factory
for a certain material (e.g. „sand“) but contains some trimmers for the precalibration (sensors
with option „T“), then the „voltage measurement“ („current measurement“) mode of „product“
menu allows to easily precalibrate the moisture sensor:
Adjust the „0“-trimmer so that the moisture sensor will emit 0V (0/4mA) at minimum moisture of
material and adjust the „%“-trimmer so that the moisture sensor will emit 10V (20mA) at
maximum moisture of material.
Preparing the samples of material:
For the calibration we need three samples of material of different moisture, prepared in plastic
(!) buckets. To keep the electrical field of moisture sensor entirely within the material during the
measurement, the material in the buckets should be at least 8-10cm thick, so that you will need
at least 2 liters of material in each bucket.
First, we kiln-dry some material of the three samples and determine the moisture by the help of
following formula:
moisture [%] = ((moist weight – dry weight) / dry weight) x 100%
Alternatively, we can use the moisture analyzer „MB45“ (ARNOLD-Automation) to determine the
moisture of the three samples.
Above formula and the kiln-drying allows us to determine the reference moistures, which we
should write down directly on the according buckets, now, to avoid any confusing later on.

Attention:
Take care, that the moisture of samples does not change during the whole calibration process!
Hint: For the very first experminents you can simulate samples of different moisture by pressing
your hand more or less strong onto the sensitive surface of moisture sensor. By the help of
„voltage measurement“ („current measurement“) of FMP-2 you can see how the signal is
changing.
Setting up a curve:
Being in the „main menu“, press the „Product channel 1“ button. Then, press the „EDIT“
button. Now, unlock the „calibration“ menu by the following sequence of keystrokes:
First, press the left arrow button (-), then the right arrow button (+), again the left arrow
button (-) and again the right arrow button (+).
Before entering calibration points for the first time, you must configure the curve by pressing the
„Set up of curve“ button in the unlocked „calibration“ menu, first. So, please enter the curve
name and a suited scale, by the help of „ABC“ and „123“ buttons. After entering of each data
press the „ENTER“ button!
Press the „ESCAPE“ button to go back to the „calibration“ menu.
Now, we can enter the calibration points by the help of „0/3“ button, which allows the calculation
of average of up to three measurements in a row:
So, please stir the material of the first bucket and press the moisture sensor onto the surface
(by a pressure of about 3kg) while slightly rotating the sensor a bit, to remove all eventually
entrapped air. Press the „0/3“ button to store the measurement. (You will notice that the button
becomes renamed to „1/3“ afterwards, to indicate that one measurement has already been
stored.)
Then, stir again the material of the bucket and press the moisture sensor onto the surface as
explained above. Press again the „1/3“ button to store the second measurement.
Then, stir again the material and store the third measurement by again pressing the „2/3“
button.

Right after that, the field „reference value“ is highlighted, to remember you to enter the
reference moisture, gained by the earlier kiln-drying.
Now, take the second and third bucket and repeat the entering of second and third calibration
point, as explained above.
To display the whole calibration curve now, press the „Calibration curve“ button. Or press the
„Calibration table“ button to display the calibration table.
Going back to the „main menu“ you will see now the correct moisture displayed on the screen.
„Dynamic“ calibration:
The calibration with samples being prepared in the plastic buckets might not exactly represent
the actual process of measuring, means the finally installed sensor might give slightly different
readings. For instance, because the moisture sensor is fit in a metal surface or metallic objects
of the installation come near to the sensitive surface of moisture sensor.
So, to obtain highest precision it might be needed to carry out a „dynamic“ calibration with the
finally installed moisture sensor, to refine the earlier „static“ calibration.
The dynamic calibration is done by the help of „silo“ button, which you will find left of „0/3“
button in the unlocked „calibration“ menu. As long as the „silo“ button is pressed, the
measurement is recorded and continuously averaged.
To gain the reference moisture of this calibration point, you must take a sample of the material,
which was measured during the pressing of „silo“ button, of course. Then, kiln-dry it and
calculate the reference moisture by the help of above formula.
